PowerVerdict takes part in the Amazon Associates Programme, an affiliate advertising arrangement under which a site can earn advertising fees by linking to Amazon.
What a price button actually does
Each "Check price on Amazon" button carries an affiliate tag. Follow one, buy the station or the reel of cable it leads to, and a share of that sale reaches us. Amazon charges you its own price: coming through this site adds nothing to it and takes nothing off it.
The click goes through this site before it reaches a store, because which store is right depends on where you are reading. A reader in Italy is sent to amazon.it and one in Spain to amazon.es, each carrying the tag registered for that marketplace. The same reasoning puts rel="nofollow sponsored" on the link: a link capable of earning is an advertisement, and it is labelled as one for anything that reads the page.
Which way the money pulls, and what holds it
Commission is a share of the sale, so a home battery is worth many times what a bag of connectors is. That pull exists and is better named than denied. Three arrangements hold against it, and each of them can be inspected rather than taken on trust:
- Where a product sits in a family has nothing to do with what it earns. Nobody looks up what a reference pays while a family is being ordered, and no list has been rearranged afterwards because one entry turned out to pay better. Where the right answer is the least expensive thing on the page — or no purchase at all, as when a panel simply needs moving out of a shadow — the page says that instead.
- A good number of the most confident recommendations here are cheap. A fuse holder genuinely rated for direct current, a reel of solar cable, a shunt: none of them earns much, and each can change more than an upgrade would. Neither price nor commission decides anything.
- Where a product has no confirmed offer on the Amazon store for your country, the button opens a search on that store rather than a listing that may have gone. That earns us less and costs you nothing.
What has never been for sale
A place in a list, a paragraph, a warmer adjective: none of these has ever been purchasable here, and none is purchasable now. Nothing on the site is sponsored. A verdict does not move because a product goes out of stock or because a rival would pay more, since nothing in how the site is built can respond to what anything pays.
On the prices themselves
A live figure on these pages comes from Amazon’s own recorded price for your market, held briefly and then read again. This shelf moves more than most: a station can hold one price for months and then drop hard for a single sale week. Read any band written into a review as the bracket it is, and take the number Amazon shows at the moment you order as the only one that settles anything.
